SPECIFICATION forming part of Letters Patent No. 609,760, dated August 23, 1898.

Application tiled December 1, 1897. Serial No. 660,371. (No model.)

T all whom t 11i/ry concern,.-

Be it known that I, GEORGE O. DRAPER, of IIopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Spindles and Bearings, of which the following description, in connection with'the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of novel means for supporting and adj usting the bolster of a spinning-spindle in the bolster-case in such manner that the proper t between the tapering pintle of the spindle and the bolster may be readily and quickly effected.

Figure l is a vertical sectional view of a spindle-bearing embodying one form of my invention. Fig. 2 is a detail, partly in elevation and section, of the bolster and spindlepintle, the bolster-support, and a portion of the bolster-case shown in Fig. l. Fig. 3 is a perspective detail of the bolster-support shown in Figs. I and 2.

The spindle S, having a tapering pintle, the bolster-case B, having a threaded shank B extended through the rail C, the nut B2 to retain the case in position, the sleeve-whirl W, secured to the spindle, and the bolster D may be and are substantiallyof usual or well-known construction. A

In the drawings the bolster support is shown as a compressible ring f, split at f' and held in position in the bolster-case by fric,

tional pressure against the Wallslthereofin vertically-adjusted position. The lower end of the bolster D rests upon this support, while the lower end of the pintle of the spindle enn tends freely through said support and rests on the step or end bearing DX.f I have provided the lower end of the bolster with a lug d, which enters the slot f of the bolster-support, and thereby the bolster is heldpfrom rotation,rotation of the support being prevented by its frictional engagement with the bolster case. The support is inserted in the case, and itis pushed down by the bolster until the end of the spindle rests on the step and the vertical adjustment of the bolster is effected.

In the construction herein described it will be obvious that the bolster is sustained by or on a support having frictional engagement with and adapted to be moved vertically in the bolster-case to thereby effect the vertical adjustment of the bolster relative to the pintle of the spindle.

Having fully described my invention, what I claim, and desire to secure by'Letters Patent, is-

l. The combination with a bolster-case, of a bolster, an expansible annular support for and located entirely below the bolster, and means to positively hold the bolster from rotation, said support being held in vertical adjustment at any point in the bolster-case solely by frictional engagement therewith.

2. A bolster-case, a bolster having a lug at its lower end, a split ring vertically movable `in and held frictionally by the bolster-case,

the` lower end of the bolster resting on said Aring with the lug projecting between the ends ofthe ring.

3. `A bolstercase, a bolster loosely held therein, anda split ring engaging the inner wall of the bolster-case at any point thereof and being held in adjusted position thereat by its frictional contact, the lower end of the bolster resting on the ring, one of said parts having a projection and the other part a notch to receive the projection, to prevent rotation of the bolster.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
